用小型凹尖氧微电极测量了狗脊髓的氧分压（PO 2）。振动和特定标记技术的使用允许消除组织压缩伪影并在胸脊髓中绘制区域PO 2。外侧白色索的PO 2值呈对称分布，灰质和背柱呈多峰分布。统计学评价显示所有这些区域具有不同的PO 2曲线;外侧白色索的PO 2值（mmHg）为61.2 +/- 12.4，背柱为55.3 +/- 19.0，脊髓灰质为30.0 +/- 13.6。这些氧分压的相对正态分布模式表明，传统的统计方法可以用来比较和评估成人脊髓中的氧扩散场。
Oxygen tension (PO2) measurements were made in the dog spinal cord with a small recessed-tip oxygen microelectrode. The use of vibration and specific marking techniques has allowed the elimination of tissue compression artifacts and the mapping of regional PO2 in the thoracic spinal cord. A symmetrical distribution of PO2 values can be shown for the lateral white funiculi; the gray matter and dorsal columns have multimodal distributions. Statistical evaluation showed all these areas to have different PO2 profiles; PO2 values (mmHg) were 61.2 +/- 12.4 for the lateral white funiculi, 55.3 +/- 19.0 for the dorsal columns, and 30.0 +/- 13.6 in spinal gray. The relatively normal distribution patterns of these oxygen tensions indicate that traditional statistical methods may be used to compare and evaluate oxygen diffusion fields in the adult spinal cord.
